GENERAL DEscriptION

The SGM72022A is a double-pole/double-throw (DPDT) transfer switch, which supports from 0.4GHz to 5.8GHz. The device features low insertion loss and high isolation, which make it suitable for high linearity and 2G/3G/4G/5G applications.

The SGM72022A has the ability to integrate DPDT transfer switch and GPIO controller on an SOI chip. Internal driver and decoder for switch control signals are offered by the GPIO controller, which makes it flexible in RF path routing and band selection.

No external DC blocking capacitors are required on the RF paths as long as no external DC voltage is applied, which can save PCB area and cost.

The SGM72022A is available in a Green ULGA-1.1×1.5-10L package.
